SKF 1204 ETN9 Self Aligning Ball Bearing- Open Type 20mm I.D, 47mm O.D

These bearings are designed to accommodate shaft deflection when running and will also cope with initial misalignment. The double row bearing is designed primarily to withstand radial load with a small capacity for axial load. Also available with ring seals (rubbing seals) made from oil-resistant, non-wearing synthetic rubber with steel reinforcement on both sides (Type 2RS1).

ETN9 and KTN9 are Open self-aligning bearings without a seal available in parallel or Taper bores.

2RS1TN9 are sealed (NBR) bearings packed with grease with a lithium thickener suitable for temperatures from -40°C to + 100°C. They are sealed for life, so should not be heated above 80°C before mounting and must not be washed out under any circumstances.

TN suffix denotes polyamide cage

This ball bearing unit from SKF can cope with both rotating shaft deflection and initial misalignment in your industrial equipment. Its high dynamic load rating of 12700 N makes it suitable for heavy radial loads while the shaft is in motion, and it can also handle small axial loads. The parallel double-row bearing unit is self-aligning, requiring no manual adjustment. This enables maintenance-free operation, saving you a lot of time and effort.

The bearings are packed with lithium-thickened grease, which is suitable for use in temperatures ranging from -40°C to +100°C.

These self-aligning ball bearings are especially suited for demanding, high-speed applications and larger operations, as their lifetime of maintenance-free use reduces the need for costly and inefficient replacements and repairs.
